Mullard 12AT7 / ECC81 - matched pair

The early 1970s Mullard 12AT7tubes in this precisely matched pair have gray plates and halo getters (VF3 series). The orange print on the glass has the Amperex globe logo and says "Made in Gt. Britain." The Blackburn, UK factory code is etched in the glass.

Both tubes test as new with balanced sections and very low noise. They are matched for both current draw (mA) and transconductance (Gm). Tubes ship in their original boxes with test results.
